3.3.3 Power supply
The CS-7 carrying pole is equipped with an internal lithium-ion battery, which supplies
power to the device itself and the mounted sensor.
The current battery level is indicated by the three green LEDs shown on the handle.
If only one LED remains lit, the battery should be charged. As soon as the battery is
empty, the device switches off without any warning.
The battery level is also displayed in the info bar of the HLE 7000 screen.
The CS-7 carrying pole can be charged in the transport case, provided the case is
connected to a power supply (see page 26).
Take one of the charging cables in the case with a round plug and connect it to the
charging socket on the carrying pole. Note the marking. You must feel the plug
engage.
The carrying pole can also be connected to the mains for charging. Use the supplied
power adapter and the VK 130 connection cable.
Insert the round plug of the cable into the charging socket on the carrying pole. Plug
the other end of the cable into the power adapter and the power adapter into an
electrical outlet.
Immediately after being connected, the device turns on and charging starts.
During charging, the battery indicator on the device will flash. The number of flashing
LEDs indicates the progress of the operation.
Once the battery is fully charged, the flashing of the three LEDs turns solid and the
I/O LED starts flashing red.
A full charge cycle takes about 8 hours.
The device will remain on even after charging is complete. It does not switch off until the
connection to the power supply is disconnected.
